US 3747830 A
Abstract
A collapsible tubular display container formed of at least one sheet of planar flexible synthetic resinous material heat sealed along the longitudinal edges thereof to form a flexible tubular body. Bead-forming synthetic resinous means is heat sealed to the continuous end edges formed thereby. Planar end wall members are pushed against the bead-forming means to be resiliently and frictionally retained thereby. One of said end walls may be provided with cord means passing through the plane thereof to assist in closing the device, and subsequently serve as a carrying means.

Ross Assistant Examiner-Stephen Marcus Attorney-Charles E. Temko [57] ABSTRACT A collapsible tubular display container formed of at least one sheet of planar flexible synthetic resinous material heat sealed along the longitudinal edges thereof to form a flexible tubular body. Bead-forming synthetic resinous means is heat sealed to the continuous end edges formed thereby. Planar end wall members are pushed against the bead-forming means to be resiliently and frictionally retained thereby. One of said end walls may be provided with cord means passing through the plane thereof to assist in'closing the device, and subsequently serve as a carrying means.

2 Claims, 6 Drawlng Figures COLLAPSIBLE SYNTHETIC RESINOUS DISPLAY CONTAINER This invention relates generally to the field of display containers, and more particularly to an improved tubular form thereof which may be stored and shipped in substantially planar condition, whereby a minimum of storage space is required.

Display containers of tubular type are known in the art, and traditionally have been formed using relatively rigid cellulosic materials to form the tubular portion thereof, the continuous end edges being headed or rolled over to form stops for cardboard end walls. While such containersare attractive, and may be produced at relatively low cost, because they are inherently of a non-nestable type, and are not collapsible, the cost of shipping the same, once manufactured has been high. In addition, difficulty is encountered in storing the devices for the same reason.

It is therefore among the principal objects of the present invention to provide an improved form of tubular container of the class described, in which the above mentioned disadvantage has been substantially eliminated.

Another object of the invention lies in the provision of an improved collapsible synthetic resinous display container, in which the tubular portion thereof may be formed of a flexible transparent or opaque heatsealable synthetic resinous planar material, the free edges of which are interconnected to form a tube which may be folded tofiattened condition when not in use.

Yet another object of the invention lies in the provision of an improved display container possessed of the above advantage, in which the cost of fabrication may be of a reasonably low order, with consequent wide sale, distribution and use.

These objects, as well as other incidental ends and advantages, will more fully appear during the course of the following disclosure, and'be pointed out in the appended claims; i

Inthe drawing, to which reference will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.

FIG. 1 is an exploded view in elevation of a first embodiment of the invention. 7

FIG. 2 is a view in perspective of the first embodiment showing the same in fully assembled condition.

FIG. 3 is an enlarged fragmentary sectional view as seen from the plane 3-3 in FIG. 2.

FIG. 4 is an exploded view in elevation showing a second embodiment of the invention.

FIG. 5 is a view in perspective'of the second embodiment showing same in fully assembled condition.

FIG.'6 is an enlarged fragmentary sectional view as seen from the plane 6-6 in FIG. 5. a

In accordance with the first embodiment of the invention, the device, generally indicated by reference character 10, comprises broadly: a rectangular side wall blank l1,first and second end walls 12 and 13, and first and second bead-forming means 15.

The side wall blank 11 is preferably of transparen polyvinyl chloride, and is bounded by side edges 17 and 18, end edges 19 and 20, as well as an inner surface 21 and an outer surface 22.

The end walls 12 and 13 are substantially similar, each being bounded by an outer surface 24, and an inner surface 25, and a peripheral edge 26. One of the end walls is provided with a central opening 27 for the engagement of a carrying cord 27a. I

The bead-forming means 14 and 15 are also made of a heat-scalable synthetic resinous material, and are of strip-like configuration. Each is bounded by an inner free edge 28 and an outer heat-sealed edge 29.

During assembly, the side edges 18 and 19 are heatsealed together, using equipment well known in the art, this operation serving to abut the end edges 30 of the bead-forming means 14 and 15 to form a continuous interior head at each end of the sleeve 31 formed thereby. Next, one of the end walls is positioned against the beadforming means, and the container may then be filled as required. The second end wall is positioned by passing the same through the respective beadforming means, and subsequently hand working the outer surface of the sleeve 31 to force the peripheral edge thereof against the free edge of the bead-forming means. This action may be assisted by resort to the cord 27a, which can be used to position the end wall in approximate location.

Turning now to the second embodiment of the invention, asillustrated in FIGS. 4, 5 and 6 in the drawing, the device, generally indicated by reference character 40 comprises first and second rectangular panels 41 and 42, respectively, each having upper and lower bead-forming members 43 and 44, respectively. Each of these members includes an outer sleeve 45 having an enclosed cord 46 therein maintained in position by a heat-sealed edge 47. The end walls 48 and 49 are captivated at the arcuate edges 50 thereof by a tab 51, so that they are permanently attached to the tubular sleeve. The walls 48-49 are of laminated type, including a fiber core 52, and first and second outer members 53 and 54, respectively, which are heat-sealed together at the periphery thereof to enclose the core ,52. The

cord 55 may be of molded type, including enlargements 56 which are passed through an opening 57 to be secured thereby.

Assembly of the second embodiment is substantially similar to the first,the end wallsbeing erected, while remaining attached to the free edges of the tube. Since the second embodiment is made of two pieces of rectangular material forrning the tube, the flattening of the tube when the device is not in use is simplified.

I wish it to be understood that I do not consider the invention limited to the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.

I claim:

1. A collapsible tubular display container comprising: at least one planar side wall, and first and second end walls; said side wall being of heat-sealable, flexible, synthetic resinous material, and being interconnected along longitudinal side edges thereof to form a tubular sleeve; synthetic resinous bead forming means interconnected by heat-sealing to the continuous edges of sleeve at each end thereof; said first and second end walls being of heat-sealable material, and of arcuate configuration, including a tab portion which is heatsealed with said bead forming means to said continuous edges of said side wall to captivate the same; said end walls being swingable about said tabs to resiliently expand said side wall at said continuous edges, and frictionally engage the same and rigidify said container.

2. Structure in accordance with claim 1, in which said side wall is formed of polyvinyl chloride.
